I don't think artursapek is arguing that these technologies are bad. There's certainly a time and place for them all, but they shouldn't be a substitute for a social situation. If I invited my friends out to a dinner and everyone brought a book with them and just read the entire time, I'd be just as pissed as if they were on their phone the entire time.

There's' also certainly something fundamentally different about browsing Facebook and Twitter over reading a book. Books are intentional - you've committed to a topic, and there's a finite amount of information to digest. When you're checking social media, you don't know what you're going to get, but it'll probably keep you occupied. You're just consuming mostly trivial information, hoping something interesting happens on your screen. It's like flipping through TV channels to pass the evening. There's nothing inherently wrong with that, but it's probably something best kept in moderation. artursapek's post is about his observations on how people are increasingly consuming this information fast food in excess.
